Basics of chemistry
the science that deals with the composition, structures, and properties of matter and how matter changes under different conditions
Chemistry
a stable, uniform mixture of two or more substances
Solution
represents the quantity of hydrogen ions.
pH
occur when an acid is mixed with an alkali in equal proportions, balancing the total pH and forming water and a salt
Acid–alkali neutralization reactions
they should not be mixed or even stored near each other Are what
Incompatible
physical properties that we can touch, taste, smell, or see.
Matter
when salt is dissolved in water, salt is the solute and water is the..
Solvent
the separation of an atom or molecule into positive and negative ions.
Ionization
When oxygen is chemically combined with a substance, the substance
Oxidized
All chemicals should be stored and disposed of in
Original containers
a chemical combination of matter in definite (fixed) proportions.
Pure substance
mixes with and dissolves in both oil and water and temporarily joins them together to form an emulsion.
Surfactant molecule
has a neutral pH because it contains the same number of hydrogen ions as hydroxide ions
Pure Water
the rapid oxidation of a substance accompanied by the production of heat and light
Combustion
Manufacturers of chemicals that are registered with either the EPA or FDA are held to strict standards for their…
Labels
a molecule containing two or more atoms of the same element (in this case, oxygen) in definite (fixed) proportions.
Elemental Molecule
contain carbon and evaporate very easily.
Volatile Organic Compund VOC
Hair and skins natural pH
pH of 5
nail product that hardens (polymerizes) to create nail enhancements is what reaction
Exothermic reaction
The location you use for _____must be well ventilated and have protective equipment available, including an eyewash bottle.
Mixing chemicals
occurs when nail polish is applied onto nails and the solvent evaporates, forming a layer or film on the nail.
Physical change
Why must estheticians know the difference between solutions, suspensions, and emulsions?
They should have an understanding of the chemical composition, preparation, and uses of cosmetics that are intended for the hair, skin, nails, and body in general.
commonly known as lye, is a very strong alkali used in chemical hair relaxers, callous softeners, and drain cleaners.
Sodium Hydroxide
When hydrogen peroxide is mixed with an oxidation haircolor, oxygen is subtracted from the hydrogen peroxide and the hydrogen peroxide is reduced. At the same time, oxygen is added to the haircolor and the haircolor is oxidized. This is an example of what?
Reducing Agent
required by law for all products sold; ___include safety information about products compiled by the manufacturer, including hazardous ingredients, safe use and handling procedures, proper disposal guidelines, and precautions to reduce the risk of accidental harm or overexposure
